Is my betta sick? He is in a 2 gallon bowl that stays at 78 degrees. There is no filter, and I've had him for four weeks now so cycling is almost over. I do a 50-75% water change once a week. Please help I will be going to Petsmart next weekend for turtle supplies so I could get some BettaFix if I need to.

4 weeks doesn't say that cycling is almost over. Tracking your ammonia/nitrite/nitrate levels is what tells you where you are.

You have 2 gallons, without filtration. You need to be changing the water more often. Small aquariums are my thing...believe me! The more changes you are doing, the better. I'm going just off your fish's appearance, which can be incredibly deceiving, but I'm guessing we are looking at ammonia levels of 2.0 parts-per-million. That's capable of doing serious damage to your little scaly friend.

You don't need BettaFix (which is just "new-betta-owner-pickpocket"). You need fresh water. Do a Google search: "Lee's sponge filter round". Lee is your new best friend. Get one, and an air pump. WTG on the temps, though! That's usually the hardest part to convince people of.

Water changes, water changes, water changes...new filtration...a little luck...and your little guy should be right as rain!

thank you for the help. I guess your are right about the cycling. I'm basing it off of a filtered large turtle tank from my experience. I know that filtration is one thing I'm not getting because I already spend enough money on other filters. I will just keep doing more water changes. Also what exactly is the possible sickness that my fish has. I realize its probably the ammonia causing it, but i just want to know whats wrong with it too. Thanks!

I agree with Mister Sparkle, ammonia.....in a 2g container the ammonia can start to rise in 3 days provided that the fish was not over fed and all uneaten food was removed after feedings.

Without filtration or some source of aeration you will not get a true cycle per se', regardless of aeration in that size container more water changes are needed as Mister Sparkle posted.

IMO/E-2g needs at least twice weekly 50% water changes with a filter and without filtration water changes need to be one 50% and one 100% weekly to provide quality water and prevent most illness and fin issues......
